The Bachelor of Science program in Statistics provides rigorous training in the theoretical foundations of statistics, statistical modeling and methodology, and applied data analysis. We also offer a Data Science option which is ideal for students with an interest in developing computational and data management skills.
As per University of Washington rules, students need a total of 180 credits in order to graduate. The University and College of Arts and Science graduation requirements can be found in your DARS report.
 The Degree Audit Reporting System (DARS) is a great tool tool to use to track your degree requirements. Here’s a quick tutorial on how to use this resource to help track your progress toward your major and graduation!
Bachelor of Science in Statistics: Minimum of 65 credits as follows
A minimum GPA of 2.0 and cumulative GPA of 2.5 is required in all courses used to satisfy major requirements.

Mathematics (25  30 credits):
 Calculus: MATH 124^{5}, MATH 125^{5}, MATH 126^{5} and MATH 224^{3 }. (students admitted autumn 2019 and earlier should replace the MATH 224 requirement with MATH 424 or MATH 318)
 Linear Algebra: MATH 208^{3 }.
 Differential equations: MATH 207^{3}. (AMATH 351^{3} may be used as a substitute)
 Mathematical reasoning & analysis: MATH 300^{3 }and MATH 327^{3}.
 Students can replace all of the above requirements by taking the Honors sequence MATH 134^{5}, MATH 135^{5}, MATH 136^{5}, MATH 334^{5}, and MATH 335^{5 }
*Students admitted Spring 2022 onward are encouraged to replace MATH 207 with MATH 318.
 Statistics (24  27 credits):
 Introductory statistics  one from STAT 311^{5} (preferred), or STAT 390^{4} or approved substitute.
 Probability theory  one from STAT 340^{4} (preferred) or both STAT/MATH 394^{3} and STAT/MATH 395^{3}.
 Statistics theory  STAT 341^{4} and STAT 342^{4}.
 Applied statistics – STAT 421^{4} and STAT 423^{4}.
 Computing (7  9 credits):
 Introductory programming: One of CSE 142^{4} or CSE 160^{4}
 Upper level programming: One of STAT 302^{3} (recommended) or CSE 143^{5} or approved substitute.
 Students in the Data Science option must take 9 credits from a slightly expanded list which includes the courses named above and also CSE 163^{4}.
 Electives:
 Regular: At least 3 courses for a total of 9 credits from the list of electives.
 Data Science:
 Visualization: One of HCDE 411^{5}, INFO 474^{5}, CSE 442^{4} , CSE 412^{4}.
 Database: One of CSE 414^{4 }or INFO 330^{5}.
 Ethics: One of SOC 225^{3/5} or CSE 491^{1} or another 1 credit seminar covering privacy, ethics, security and societal impacts of data science.
 Two courses from STAT 435^{4}, STAT 425^{4}, STAT 403^{4}.
Restriction on double majors:
 No double majors with MATH
 No double majors with ACMS (any track)
 No postbac students
Planning Your Program of Study
The statistics major may be completed in 2 years. The following schedule shows how a student who discovers statistics after arriving at UW may still be able to complete all the necessary coursework for submitting an application.
Sample Program
Autumn  Winter  Spring  Summer  

Freshman 



Take a break 
Sophomore 



Take a break 
Junior 



Do an internship summer of junior year 
Senior 



Footnotes:
^{1:} MATH 300 is the only course that teaches the techniques of writing mathematical proofs. Students must take this class immediately upon being admitted to the major as subsequent courses will assume that students are familiar with how to write a proof.
^{2} : CSE 416 "Introduction to Machine Learning'" does not fulfill major requirements, however, alumni have noted that the course was helpful for summer internships/jobs. STAT 435 "Introduction to Statistical Machine Learning" is best taken after completing the applied statistics sequence STAT 421 and 423.
^{3 : }STAT/MATH 396 "Probability III" is a good elective for those considering a PhD in statistics.
Additional comments:
 Students entering with AP credit for MATH 124 or MATH 124  MATH 125 are encouraged to take a look at the exam archives for 124 and 125 before making a decision on whether or not to skip these foundational courses. The calculus courses at UW emphasize problem solving and geometry. As such, they go beyond most AP calculus curricula.
 STAT 220, STAT 221 or STAT 290 are never allowed as a suitable substitute. STAT 311 is a better choice than STAT 390 for statistics majors as it emphasizes statistical reasoning.
 The combination of both STAT/MATH 394 and 395 may be used to replace STAT 340 as a prerequisite to STAT 341.
 All Statistics majors MUST complete STAT 342 prior to enrolling in STAT 421 and 423. (STAT 390 or STAT 509 are NOT sufficient for a Statistics major to enroll in either STAT 421 or STAT 423).
 The placement ofMATH 327 in the above schedule will be beneficial for most students. Mathematically mature students may consider taking MATH 327 in their junior year.
